What the model said

I'd suggest **#0066CC** (a clean, medium blue) for a button. It's a classic choice that's widely recognized as interactive, has good contrast against light backgrounds, and works well across different contexts. 

If you want something different, here are some alternatives:
- **#28A745** - green for positive/success actions
- **#DC3545** - red for destructive/warning actions  
- **#6C757D** - gray for secondary buttons

What's the button's purpose or the overall design context?
